JDK
JDK ( Java Development Kit ) is Sun Microsystems for the Java developer products. Since the introduction of Java, JDK has become the most widely used Java SDK. JDK is the core of Java, including the Java runtime environment, Java and Java foundation class library. The first step is to learn Java JDK. While written specifically to run on the X86 platform of Jrocket on the server running efficiency than the Sun JDK much better. From SUN JDK5.0, provides a generic and other useful functions, their version is also constantly updated, operational efficiency has been greatly improved.
JDK is the core of Java, including the Java runtime environment ( Java Runt ime Envirnment ), a pile of Java tools and Java base class library ( rt.jar ). No matter what the Java application server in essence is a built-in version of the JDK. Therefore, mastering JDK is the first step to learn Java. The most popular JDK Sun released JDK, in addition to Sun, there are many companies and organizations have developed their own JDK, such as IBM developed JDK, BEA Jrocket, and GNU JDK, organization development. The IBM JDK contains JVM ( Java VirtualMachine ) efficiency than the Sun JDK JVM contains a much higher. While written specifically to run on the X86 platform of Jrocket on the server running efficiency than the Sun JDK much better. But anyway, we still need to take Sun JDK master.
In 1997 Servlet technology is generated and then produce JSP, Java against PHP, ASP and so on the server-side language brought chips. In 1998, Sun released EJB1.0 standard, so J2EE platform three core technologies have appeared. Then, in 1999, Sun released the first version of J2EE. And by the end of 1999 and released the J2EE1.2, released in 2001 by J2EE1.32003 published J2EE1.4. 2.J2EE1.3 J2EE1.3 architecture, which mainly contains the Applet Application Client container, container, Web and EJB containers, and includes the Web Component, EJB Component, Application Client Component, JMS, JAAS, JAXP, JDBC, JAF, JavaMail, JTA and so on technology as foundation. 1.3 introduces several notable features: the Java message service ( JMS is defined in a group of API ), J2EE connector technology ( definition of extended J2EE service to a J2EE application standard ), the XML parser in a group of Java API, Servlet2.3, JSP1.2 has also made the performance of expansion and optimization, a new CMP component model and MDB ( Bean news ). 3.J2EE1.4 J2EE1.4 general framework and J2EE1.3 are consistent, 1.4 adds support for Web services, Web is the main Service, JAX-RPC, SAAJ, JAXR, the EJB message passing mechanism were improved (EJB2.1 ), deployment and management tools to enhance ( JMX ), as well as a new version of the Servlet2.4 and JSP2.0 such that Web applications easy. 4.JAVA EE 5 JAVA EE 5 has many notable characteristics. One of them is the new Java Standard Tag Library ( JSTL ) 1.2 specification. JSTL 1.2 is the key to the unified expression language, it allows us to JavaServer Faces ( JSF ) using JSTL's best features.
JDK contains basic components include: javac - compiler, source program into byte code Jar - packing tool, will be related to class files into a file package Javadoc - document generator, from the source notes extracted document JDB - debugger, Java - checking tools run the compiled Java program ( . Class suffix ) appletviewer: applet browser, an implementation of HTML file on the Java small program Java browser. Javah: can call a Java procedure C process, or can be Java program called C process header file. Javap: Java disassembler, display compiled class file access functions and data, while displaying the byte code meaning. Jconsole: Java system debugging and monitoring tools.
Java virtual machine program: responsible for parsing and run the Java program. In various operating system platforms have corresponding Java virtual machine program. In the Windows operating system, the program for the file name java.exe.
The Java compiler program: responsible for compiling Java source program. In the Windows operating system, the program for the file name javac.exe.
The JDK class library: provides the most basic Java and various types of practical class. Java.lang, java.io, java.util, java.awt and javax.swing classes in the package are located in the JDK class library. On the Java package concept see chapter second section 2.5 ( package declaration statement ).
Assume that JDK mounted to the local root directory for the C : \ JDK, in C: \ JDK \ bin directory is a java.exe and javac.exe files, they are respectively the Java virtual machine program and Java compiler program.
In order to facilitate in DOS command line directly run Java virtual machine program and Java compiler program, you can put C : \ JDK \ bin directory is added to the operating system PATH system environment variables.
Java.lang: This is a system based on class, such as String are inside this, this package is the only one without introducing ( import ) can be used to package java.io: there is all input and output relevant categories, such as file operations such as java.nio; in order to improve the IO package in the function, improve the IO package performance and wrote a new package, such as NIO non clogging application : it is concerned with the network class, such as URL, URLConnection etc.. Java.util: This is the system auxiliary class, especially the collection class Collection, List, Map etc.. Java.sql: This is the operation of the database category, Connection, Statement, ResultSet etc.
The Java runtime environment installation and test and HelloWorld implementation. 1 J2SDK 1.6.0_21 or later ( http: / / java.sun . Com, download the Java Documentation suggested at the same time, this is Java help documentation ) 2 running just download the official installation installation program ( the following hypothesis is installed in the C: \ jdk1.6.0_21 \, suggested the installation path with no spaces, should not be installed in the \ Program Files directory! ). The 3 set of operating environment parameters: a. If Win95 / 98, in the \ autoexec.bat most behind add these 3 lines statement: set JAVA_HOME = C: \ jdk1.6.0_21 \ set PATH = %JAVA_HOME% \ bin; %PATH% set CLASSPATH; %JAVA_HOME% =. \ lib note: - DOS command Notepad available C: \ autoexec.bat open Notepad, join the above 3 line statement. B. If Windows2000, XP or Win7 system, use the right mouse click "my computer" - > properties - > Advanced - > environmental variables system variable - > New > variable name variable values: JAVA_HOME: C: \ jdk1.6.0_21 \ system variable - > New > variable names: CLASSPATH: variable values.; %JAVA_HOME% \ lib system variable - > Edit - > variable names: Path values in variables in the front plus: %JAVA_HOME% \ bin; ( CLASSPATH is English . "" followed by a semicolon, said the current path. ) ( using the command line method to set environment variables, only for the current window force) 4 using a text Editor ( for example: edit . COM / notebook / UltraEdit / EditPlus ) write the following code, and preservation of the document: HelloWorld.java ( must be sized to write correctly! Assuming C : \ test \ HelloWorld.java ) / * HelloWorld.java * / public class HelloWorld {public static void main ( String Arg [ ] ) {System.out.println (" Hello, World!" ); } } 5 open a DOS window, jumping into the HelloWorld.java directory of the C: \ CD \ test 6 compiler HelloWorld.java HelloWorld.class C: \ test > javac HelloWorld.java 7 running HelloWorld.class C : \ test > java HelloWorld Hello, World!

JDK
JDK(Java Development Kit)是Sun Microsystems针对Java开发员的产品。自从Java推出以来，JDK已经成为使用最广泛的Java SDK。JDK是整个Java的核心，包括了Java运行环境，Java工具和Java基础的类库。JDK是学好Java的第一步。而专门运行在x86平台的Jrocket在服务端运行效率也要比Sun JDK好很多。从SUN的JDK5.0开始,提供了泛型等非常实用的功能，其版本也不断更新，运行效率得到了非常大的提高。
JDK是整个Java的核心，包括了Java运行环境（Java Runt ime Envirnment），一堆Java工具和Java基础的类库(rt.jar)。不论什么Java应用服务器实质都是内置了某个版本的JDK。因此掌握JDK是学好Java的第一步。最主流的JDK是Sun公司发布的JDK，除了Sun之外，还有很多公司和组织都开发了自己的JDK，例如IBM公司开发的JDK，BEA公司的Jrocket，还有GNU组织开发的JDK等等。其中IBM的JDK包含的JVM（Java VirtualMachine）运行效率要比Sun JDK包含的JVM高出许多。而专门运行在x86平台的Jrocket在服务端运行效率也要比Sun JDK好很多。但不管怎么说，我们还是需要先把Sun JDK掌握好。
1997年Servlet技术的产生以及紧接着JSP的产生，为Java对抗PHP，ASP等等服务器端语言带来了筹码。1998年，Sun发布了EJB1.0标准，至此J2EE平台的三个核心技术都已经出现。于是1999年，Sun正式发布了J2EE的第一个版本。并与1999年底发布了J2EE1.2，在2001年发布了J2EE1.3，2003年发布了J2EE1.4。2.J2EE1.3 J2EE1.3的架构，其中主要包含了Applet容器，Application Client容器，Web容器和EJB容器，并且包含了Web Component，EJB Component，Application Client Component，以JMS，JAAS，JAXP，JDBC，JAF，JavaMail，JTA等等技术做为基础。1.3中引入了几个值得注意的功能：Java消息服务（定义了JMS的一组API），J2EE连接器技术（定义了扩展J2EE服务到非J2EE应用程序的标准），XML解析器的一组Java API，Servlet2.3，JSP1.2也都进行了性能扩展与优化，全新的CMP组件模型和MDB（消息Bean）。3.J2EE1.4 J2EE1.4大体上的框架和J2EE1.3是一致的，1.4增加了对Web服务的支持，主要是Web Service，JAX-RPC，SAAJ，JAXR，还对EJB的消息传递机制进行了完善（EJB2.1），部署与管理工具的增强（JMX），以及新版本的Servlet2.4和JSP2.0使得Web应用更加容易。4.JAVA EE 5JAVA EE 5拥有许多值得关注的特性。其中之一就是新的 Java Standard Tag Library (JSTL)1.2规范。JSTL 1.2的关键是统一表达式语言，它允许我们在 JavaServer Faces (JSF) 中结合使用JSTL的最佳特性。
JDK包含的基本组件包括：javac–编译器，将源程序转成字节码jar–打包工具，将相关的类文件打包成一个文件javadoc–文档生成器，从源码注释中提取文档 jdb – debugger，查错工具java–运行编译后的java程序（.class后缀的）appletviewer：小程序浏览器，一种执行HTML文件上的Java小程序的Java浏览器。Javah：产生可以调用Java过程的C过程，或建立能被Java程序调用的C过程的头文件。Javap：Java反汇编器，显示编译类文件中的可访问功能和数据，同时显示字节代码含义。Jconsole: Java进行系统调试和监控的工具.
Java虚拟机程序：负责解析和运行Java程序。在各种操作系统平台上都有相应的Java虚拟机程序。在Windows操作系统
